2 Claims. 1

My present invention relates to apparatus for determining the size of a golf ball core.

In forming a. golf ball core to be enclosed in a cover, a rubber thread is wound under tension onto a center. This has been accomplished by placing the center on a pair of rotating driving rolls and confining the center and the core being formedthereon by a displaceabl'e idler roll or pair of rolls which are displaced as the core is wound and built up to an increasing size. It is desirable that the winding shall stop when the core has reached the dimensions which have been determined for it so that its dimension shall have the proper relation to the center and to the core.

My invention provides apparatus by which this is accomplished accurately and by which the winding is instantly stopped when the predetermined dimension is attained. The invention also provides means whereby the dimension at which the winding is stopped may be readily changed or adjusted.

In my invention I provide a support and a carriage for the idler roll or rolls slidable relatively on the support as the core increases. The support carries an electric micro-switch and an adjusting means for moving the switch toward or from the rolls. The switch is provided with an actuating stem. Between the actuating stem and the rolls is a stop or rod movable with the rolls into contact or abutment with the actuating stem of the switch and so spaced that it will move the stem and thereby operate the switch when the core has been wound to its predetermined size. The operation of the switch instantly stops further winding of the core by shifting or uncoupling the driving mechanism of the driving rolls. The core is thus brought to the proper dimension and all cores wound on the machine are of uniform dimensions. These dimensions may be modified by shifting the microswitch on its support toward or from the winding rolls.

The various features of the invention are illustrated, by way of example, in the accompanying drawings in which Fig. 1 is a side elevation of a part of a golf ball winding machine embodying the invention;

Fig. 2 is a front elevation of the golf ball winding machine of Fig. 1;

Fig. 3 is a vertical section on the line 3-3 of Fig. 2;

Fig. 4 is a vertical section on the line 44 of Fig. 3;

Fig. 5 is a section on the line 55 of Fig. 4.

In the embodiment of the invention illustrated in the accompanying drawings, the golf ball core l0 being wound is supported on a pair of rolls H and 52, one of which, for example roll H, is mounted on a shaft l3 driven by a pulley i4. Thread 15 is supplied to the core through a suitable tensioning device which holds it under constant tension as it is being wound. The rolls are mounted in a suitable frame. it? having a plate 23' abovethe rolls. The core is held in place on the rolls l2 and H by a pair of idle rolls it and i6 which rotate freely with the rotating core. The rolls. l8. and i9 are mounted on a carriage 20 between the rolls and support plate I i. The carriage is guided by a. guiding. stem or rod 2! extending upwardly through. a tubular guide 22 on the plate H. The rolls, l8. and I9 are pressed downwardly onto. the core ill by their weight and that of. the carriage and stem, or by suitable springs not shown.

As the core increases in size by successive windings, as indicated in Fig. 1, it lifts the rolls l8 and i9 and the carriage 20 so that the rise or" the carriage is a measure of the increase in size of the core.

Adjustably mounted on the supporting plate and tubular guide 22 is a microswitch 23 having a downwardly extending operating stem 2 The lower end of the stem is directly above a slidable rod 25 slidably extending through the plate !1 to the upper surface of the carriage 29. As the carriage rises it carries the rod 25 upwardly and upon reaching the limit set for the size of the core it engages the stem 24 lifting it and operating the microswitch 23.

The microswitch 23 is adjustable vertically so that it is operated precisely at the point when the core attains its predetermined diameter or dimension, and the position of the microswitch on the support I? is therefore adjusted and set to attain this predetermined size of core. For this purpose the microswitch 23 is mounted on a lever 26, one end of which is pivoted on a fixed pivot pin 2'! on a bracket 28 standing upwardly from the supporting plate ll, Fig. 2. The other end of the lever 26 extends through a slot 29 formed at the opposite side of the bracket 23 and clamping plate 3t. This end of the lever is pressed upwardly by a spring 3|. Its upward movement is limited by a screw 32 threaded downwardly into the bracket 23 and turned by a knurled head 33. By turning the screw 32 the lever 26 may be tilted upwardly or downwardly about the pivot pin 21.

When the end of the lever has been tilted to the required position it is clamped in this position by a screw 34 extending through the bracket 28 through a slot 35 in the lever 26 and is threaded into the clamping plate 30. When 3 clamped in position the lever is firmly and securely held to position the microswitch at the height required for the desired size of the golf ball center.

When the microswitch is actuated by the rod 25 it energizes a circuit, indicated at 36 in Figs. 2 and 3, to actuate an electromagnetic valve 3'! acting on a. belt shift 38, thereupon the belt shifting mechanism 38 shifts the belt from the driving pulley 13 to an idler pulley 39 and the rotation stops. The completed core may then be removed and replaced by a center to be wound.

The microswitch operates instantly when its operating stem is raised to the operating level and the belt shifter 38 thereupon immediately shifts the belt and terminates the driving of the winding rolls. This enables the core to be wound to an exact dimension.

It will be understood that the microswitch may be used either to open or close the circuit 36, the valve 37 being arranged accordingly.

Having described my invention, what I claim 1. A golf ball winding machine which comprises a pair of parallel, spaced, ball supporting winding rolls, a carriage above said pair of winding rolls, a pair of parallel idle rolls mounted on said carriage above and parallel to said winding rolls and positioned to engage symmetrically a golf ball supported on said winding rolls, said idle 1:

rolls and carriage being displaceable with the increase of the size of the ball core, a switch to control the stopping of said winding machine, a

stop mounted on said carriage in position to actuate said switch when said carriage is displaced to a predetermined position, a lever on which said switch is mounted and an adjusting screw to tilt said lever and switch toward and from said stop.

2. A winding machine for golf ball cores which comprises a pair of supporting and driving rolls, a fixed support above said driving rolls, a carriage carrying a pair of parallel idler rolls parallel to said supporting and driving rolls and positioned to ride symmetrically on a core supported on said supporting and driving rolls and slidably carried by said support, an electric circuit comprising a microswitch having an operating stem and adiustably mounted on said support to move said operating stem toward or from said rolls, a

- rod on said carriage positioned to engage and actuate said operating stem when said carriage moves to a predetermined position from said driving rolls, and a power shifting element actuated by said circuit to disconnect said rolls when said microswitch is actuated.
